For adjustably sustaining the stack of blanks tion particularly tosupport 51, a description a .the combination of a hopper for holding astack of fastener blanks, a table for receive blank and push out from`the, upper face B so that only one at a time'will be removed by blades9CL and 9b as those blades move forwardly under said stack, oppositeblank supports 50,51 are provided. Directing attenof which will sufficefor both, said' support comprises rail 51EL Ylying below presser foot 45and in parallelism therewith.Al Said rail is carriedv by arm 51bextending at right angles' therefrom, and said larmis .pivotallymountedl at Y52 on the front of hopper 8.V

The outer end of arm 51b is adjustable up and'down by means of screw53,and spring 5.4 offers a yielding resistance to said screw and arm. Bythis means rail 51may be For locating punching station, adjustable stops55,56 are provided.

' The operationV of my improved machine' is as follows: A supply offastener blanks B having beeninserted in hopper 8, cam shaft v6 isstarted rotating-in clockwise direction,

Fig. 1. Assuming that slide 9 and blades 9a,

V9b are in the position o f Fig. 1, the lowermost blank in hopper 8 willlie with its long Varms in notchesV 40, 41 ofsaid blades, re-vspectively,'blank support rails 50a, 51a'sustaining said blank at jaheight which will present the lupper face Iof thev blank'just above theplane of the upper faces of bladesv 9a, 9b. Then as said blades moveforwardly tothe right, Figs. 1 and 2, they will/carry said Ablank alongunder presser feet 44, 45 to the punching station, over punches 25, 25,Fig. 4. Die block 17 then `descends into engagement with the upper faceofthe blank, holding thatk blank securely against table 10. Punches 25,25 then ascend, penetrate said thereof Vthe usual projecting prongs. Dieblock 17 then retires upwardly, said prongs being stripped therefrom bypresserfeet 44,

45, `and punches `25, 25 follow said die block a distance sui'licient tolift the blank out of engagement with notches 40,41 ofv blades 9a, 9b,thereby lifting presser feet 44, slightly, Fig. 4,`the friction of saidprongs yagainst said punches being sui'licient to maintain the relationof the fastener and punches against the weak presser lfoot springs 48,49.

While said punched blank is thus held above blades 9a, 9bsaid bladesretire to the left,

back to the position of'F ig. l toreceive'an- Y other blank in theirnotches. Punches 25, 25

.then retire downwardly and the blank rests upon table 10, ready to bedischarged vinto ports under said stack of blanks, and means foradjusting said supports for lowering said blanks.
